Do you see a "Profile" link at the top of the forums window? You can change your avatar there, and you should be able to upload an avatar from your local workstation.
Let me know if you have any more questions or troubles with this!

When I try to upload the avatar file there are no permission and unable to write error messages, and the file fails to upload.
